please review the following feature design. It introduces a global
account lockout, while trying to keep the replication traffic minimal.
In my opinion for a real global account lockout the basic lockout
attributes have to be replicated otherwise the benefit is minimal: an
attacker could perform (maxFailedcount -1) login attempts on every
server before the global lockout is set. But the design page describes
how it could be done if it should be implemented - maybe the side effect
that accounts could the be unlocked on any replica has its own benefit.
